What's the best treatment for diverticulitis?

Ab, I've fluids... Acute diverticulitis commonly presents as left lower abdomen pain, fever, tenderness on exam. Cause is inflammation/infection of a diverticulum, which is a pouch coming off the colon wall (extremely common and no sx). Treatment is bowel rest (clear fluids only perhaps), IV fluids, antibiotics. If mild case, maybe outpt. If severe or abscess forms, possibly surgery. If recurrent x 3, surgery.
